[Jason] Some organizations (such as financial institutions) may have good security reasons to disallow password managers.
Just to note that the new NIST advice [1] came out on the 22nd:
"Verifiers SHOULD permit claimants to use “paste” functionality when entering a memorized secret. This facilitates the use of password managers, which are widely used and in many cases increase the likelihood that users will choose stronger memorized secrets." [2]
I assume it will take a while to filter through, but is NIST an organisation that places like banks would listen to in the US?
Cheers,
Alastair
